The new law puts a set of recently adopted regulations into statute, and takes them a step further. It specifies that the state will not pay for elective abortions. It also limits the term “medically necessary” to cases where a woman’s life or physical health is at risk. The regulations had included a mental health exception.

The new law is expected to be challenged in court. Planned Parenthood and the American Civil Liberties Union are already suing the state over the existing regulations, arguing that they violate the Constitution’s equal protection clause.

Last year, the state’s Medicaid program covered about a third of the 1,500 abortions performed in Alaska.
